Answer: $1,170ft^2$

Step-by-step explanation:

We know that the area of the living room can be calculated with the formula for find the area of a rectangle. This formula is:

$A_1=l_1*w_1$

Where:

$l_1$ is the lenght of the original living room, and $w_1$ is the width of the original living room.

If he creates the addition that causes the dimensions to triple, then the new area of Garrett’s living room is:

$A_2=(3l_1)(3w_1)\\A_2=(3*13ft)(3*10ft)\\A_2=1,170ft^2$
